A triple fatality accident was reported in Calaveras County Saturday evening. CHP say a trio of occupants in a 1993 Dodge Ram pick up were traveling on Railroad Flat Rd going 50 to 55 miles per hour when, for an unknown reason, the 70 year old male driver, allowed the truck to leave the roadway. He then overcorrected and sent the pick up into a slide. The truck then continued the slide across the road and into a large oak tree.  The driver and his 61 year old female passenger, both from Mountain Ranch, were dead at the scene. The third occupant of the truck, a 42 year old woman from Marysville, died several hours later at the hospital after being flown to Mercy San Juan Hospital. The cause of the collision is under investigation, however the CHP report does state that alcohol use is suspected.
